The final model has four variables: age, encephalopathy, serum bilirubin, and serum albumin to obtain a risk score (R) for each patient using the formula R = (0.0484 × [Age in Years] + 0.469 × [encephalopathy] + 0.537 × Loge [Bilirubin in μmol/L] - 0.052 × [Albumin in g/L]. This evidence concerns the gene ALB and Encephalopathy.
